[0026] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0027] Embodiment 1

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a hot compress device for treating a knee joint, comprising a plate body 1, which can be bent into a cylindrical body, and fixing plates 3 are respectively provided on both sides of the top and bottom of the plate body 1 along the width direction, and the fixing plate 3 can be bent and fitted on the knee joint, and an air bag 5 is fixedly bonded to the outer surface of one side of the fixing plate 3 along the width direction, and when the fixing plate 3 is bent and folded, the air bag 5 is located in the inner ring and fits the knee joint, and an inflation component 4 is connected to one end of the air bag 5, and the inflation component 4 is used to inflate the air bag 5, and a limiting member 6 is fixedly provided on the end of the outer surface of the side of the fixing plate 3 away from the air bag 5 in the vertical direction, and the limiting member 6 is used to limit the inflation area of ​​the air bag 5, and the limiting member 6 and the inflation component 4 are arranged at the same end, and when the fixing plate 3 is bent and folded, the top of the limiting member 6 is clamped at the corresponding position of the other end of the fixing plate 3, and compresses the air bag 5.

[0029] In this embodiment, the plate body 1 is first bent. After the plate body 1 is bent, the plate body 1 cannot completely fit the outer skin of the human knee joint because it is a plane. The fixing plate 3 is then bent to fit the leg near the knee joint. After that, the limiting member 6 is used to tightly press on the airbag 5, so that the airbag 5 in the overlapping section of the fixing plate 3 cannot be inflated. When the inflation area of ​​the airbag 5 is limited, the inflation component 4 is used to inflate the airbag 5. At this time, the airbag 5 installed on the non-overlapping section of the fixing plate 3 is inflated until it is squeezed and contacted with the leg. When the entire device is fixed, the medicine is injected through the medicine inlet 2 for hot compress.

[0030] In this embodiment, the airbag 5 and the inflation component 4 can be used to inflate the airbag 5 to better fit the skin of the leg after the fixing plate 3 is bent and wrapped around the leg. While strengthening the fixation, it can also improve the patient's skin comfort. The setting of the limiting member 6 solves the problem of the fixing plate 3 being stretched out due to the inflation of the airbag 5 after the fixing plate 3 is overlapped. The limiting member 6 can compress the airbag 5 so that the overlapping section of the airbag 5 is no longer inflated.

[0031] Embodiment 2

[0032] This embodiment is further optimized on the basis of the first embodiment, and the same parts as the above technical solution will not be repeated here. Figure 1 , Figure 2 As shown, in order to better realize the utility model, the following setting method is particularly adopted: in this embodiment, the inflation component 4 includes an inflation tube 401 connected to the airbag 5, the inflation tube 401 is connected to the airbag 5, and a squeezing ball 402 is threadedly connected to one end of the inflation tube 401, and a one-way valve 403 is fixedly installed on one end of the squeezing ball 402. When the squeezing ball 402 is squeezed, the airbag 5 is filled with gas and expands, thereby squeezing the knee joint.

[0033] In this embodiment, after the plate body 1 is bent and wraps around the knee joint, the two fixing plates 3 are bent again. After the two ends of the fixing plates 3 are overlapped, they are tightly pressed on the airbag 5 by the limiting member 6, so that the airbag 5 in the overlapping section of the fixing plate 3 cannot be inflated. When the inflation area of ​​the airbag 5 is restricted, the inflation can be started by pressing the squeezing ball 402. At this time, the airbag 5 installed on the non-overlapping section of the fixing plate 3 is inflated and expanded until it is squeezed and contacted with the leg. The set airbag 5 can fit the shape of the leg when inflated, and when the device is fixed to the patient's leg, the patient's comfort can also be improved.

[0034] Embodiment 3

[0035] This embodiment is further optimized on the basis of the first embodiment, and the same parts as the above technical solution will not be repeated here. Figure 1 , Figure 2 , Figure 3As shown, in order to better realize the utility model, the following setting method is particularly adopted: in this embodiment, the limiting member 6 includes a straight line segment 601 fixedly arranged along the vertical direction on the end of the outer surface of the fixing plate 3 away from the airbag 5, and the top of the straight line segment 601 is fixedly connected with a bending portion 602, the bending portion 602 and the straight line segment 601 are integrally formed, and a snap-in groove is formed between the bending portion 602 and the straight line segment 601, and the snap-in groove is snap-connected to the corresponding position of the other end of the fixing plate 3.

[0036] The limiting member 6 is made of rubber material as a whole. When the bending portion 602 is engaged with the fixing plate 3 , an interference fit is formed between the limiting member 6 and the fixing plate 3 .

[0037] In this embodiment, after the plate body 1 is bent and wrapped around the knee joint, the two fixing plates 3 are bent again. After the two ends of the fixing plates 3 are overlapped, the limiting member 6 is set so that the snap-in groove formed between the straight section 601 and the bent portion 602 is snapped onto the fixing plate 3. The limiting member 6 in the accompanying drawing is only a schematic diagram. The sizes of the bent portion 602 and the straight section 601 are set according to the actual thickness of the fixing plate 3. The limiting member 6 is made of rubber as a whole, which has a certain elasticity and is convenient for interference fit with the fixing plate 3. This allows the bent portion 602 to be tightly clamped on the fixing plate 3, so that the straight section 601 is tightly pressed on the airbag 5, making it impossible for the airbag 5 in the overlapping section of the fixing plate 3 to be inflated. The setting of the limiting member 6 can prevent the airbag 5 in the overlapping section from expanding after the fixing plate 3 is overlapped.

[0038] Embodiment 4

[0039] This embodiment is further optimized on the basis of the first embodiment, and the same parts as the above technical solution will not be repeated here. Figure 1 , Figure 4 , Figure 5 As shown, in order to better realize the present utility model, the following configuration is particularly adopted: In this embodiment, a plurality of drug inlet holes 2 are evenly opened on the plate body 1, and the drug inlet holes 2 are used for injecting drugs.

[0040] Two layers of non-woven fabric 7 are detachably connected along the width direction on the outer surface of one side of the plate body 1, and the non-woven fabric 7 covers the drug inlet hole 2. When the plate body 1 is bent and folded, the non-woven fabric 7 is located in the inner ring, and a drug storage layer is formed between the two layers of non-woven fabric 7.

[0041] The drug storage layer formed between the two layers of the non-woven fabric 7 is filled with a sponge, and the sponge is used to absorb the injected drug. The cross section of the drug inlet 2 is an isosceles trapezoid, and the bottom of the trapezoid faces the outside of the plate body 1.

[0042] The cross section of the medicine inlet 2 is an isosceles trapezoid, and the bottom of the trapezoid faces the outside of the plate body 1 .

[0043] In this embodiment, the setting of the drug inlet 2 and the drug storage layer refers to the disclosure recorded in the patent document with the announcement number CN216060949U. When the plate body 1 and the fixing plate 3 are bent and fitted on the knee joint, the drug is injected through the drug inlet 2. The cross-section of the drug inlet 2 is an isosceles trapezoid, and the bottom of the trapezoid faces the outside of the plate body 1. The diameter of the inlet end is larger than the diameter of the outlet end. The drug can flow onto the non-woven fabric 7, and the drug under the leg can be reduced from flowing back from the drug inlet 2 to cause waste. In the patent document with the announcement number CN216060949U, in order to prevent the drug from flowing out from the upper and lower ends of the cylinder, sealing strips are further provided on the inner surfaces of the upper and lower ends of the cylinder. The sealing strips can be in close contact with the leg skin to reduce drug waste. Reference can be made here.

[0044] After the medicine enters the medicine inlet hole 2, it can be absorbed by the cotton, preventing the medicine from being affected by gravity and gathering below. At the same time, the cotton is in close contact with the skin of the knee joint through a layer of non-woven fabric 7, which can have a good hot compress effect and improve the comfort of the patient's knee joint skin. After the hot compress is completed, the non-woven fabric 7 and the cotton can be removed and replaced with clean ones for other patients to use. The detachable chain connection here can be bonded with adhesive strips.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
